Ok I have done everything on earth from replacing hoppers to all switches to nodes I have followed the wiring diagram I have had this system from day one it works like a dream when you have two of the hoppers isolated from the third, the second you add the third to the system all hell breaks loose and no I have tried turning bridging off on all hoppers but one. There has to be some kind of technical glitch in here that I am missing that make the hole darn thing work harmoniously that I am missing. Someone out there must know the answer to this question because dish sure does not. Oh also I have 2 hoppers with sling one hopper 2000 and 3 joeys I have downsized. edit and got rid of all extra Ethernet.
